I have always been motivated to eat better and exercise more because I am scared of getting diabetes complications. I find it helpful to be realistic, in that if I allow my HbA1c and other indicators to stay above normal, I am risking those complications. I would rather know the truth as early as possible, than find out later that there was something I could have done to prevent it.
Blindness, amputations and dialysis are the extreme complications, but I would also not like to have continual skin and other infections, neuropathy that affected my stomach and bowel function, numbness or tingling in my feet, vision problems, and knowing that every cold or tummy bug is going to be more severe and last longer than it otherwise would. Eating healthy is a small price to pay to avoid these things.
